CHARLES F. BOTTO, OF PHILADELPHIA, PENNSYLVANIA.

TUBE CUTTING ANIDTI-IREADING TOOL.

To all whom t may concern.'

Be it known that I, CHARLESF. Bor'ro,.a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Tube Cutting and Threading Tool, of whichthe following is a specication.

My invention consists of'a device adapted to cut metallic tubes (orrods) with screwthreads thereon, or to cut them through to sever thesame. To this end, the device is equipped with a two part cutter ofreversible nature, and means for interlocking certain members of thedevice, whereby only the operations of screw-threading or the sever ingmay be effected, witlrout interfering with each other.

The invention is satisfactorily illustrated in the accompanyingdrawing,'but the important instrumentalities thereof may be varied, andso it is to be understood that the invention is not limited to thespecific details shown and described. l

Figure 1 represents a top plan view of a screw-threading and severingdevice embodying my invention.

Fig. 2 represents a longitudinal vertical section thereof on line 2-2Fig. 1.

Fig. 3 represents a bottom plan view thereof. e

Fig. 4 represents a longitudinal vertical section of a portion on line4-4 Fig. 2.

Fig. 5 represents alongitudinal vertical section of a portion on line 55 Fig. 1.

Fig. 6 representsv a perspective view of the two part cutter employed.

Fig. 7 represents a side elevation of a portion of the members shown inFig. 4.

Similar numerals of reference indicate corresponding parts in theigures.

Referring to the drawings :f-

1 designates the stock of the device, the saine consisting of the openframe 2through which the tube 3 may be passed, o ne sideof l said framehaving therein the internally threaded boss 4 in which is tted the screw5, the inner end whereof is swiveled `to the forked head 6, which latterserves to engage said tube and clamp it r'mly to said frame.

The stock l has `thereon the handle 7 for holding the same, and thescrew 5 has thereon the handle 8 for rotating the same vas is evident.

On the frame 2 .is the plate 9 which is secured thereto by the screws10, and having on the central portion thereof the annular Specication ofLetters Patent.

flange 11 which freely embraces the shoulder 12 on the base of therotatable sleeve or cyl-- inder 13, which rests freely on the top wallsof the frame 2, the tube 3 being adapted to 4pass through said sleeve.

On the side of the plate 9 and flange ll 1s the member-14 forming aguide for the spring-pressed plunger or pin-like member -15 whose `innerend is adapted to pass 'through said flange and interlockingly enter therecess 16 in the adjacent portion Vof the sleeve 13, so as to preventrotation of the latter whene required.

Projecting'from the side of said plunger 15 isthe nger 17, and in themember 14 the slot 18 into which when the plunger is Y`drawn out -saidfinger may be entered, whereby the plunger is held disconnected from thesleeve 13 when the latter may be rotated when required.

When the plunger is rotated in the proper direction, the finger 17 isremoved from the vslot 18 and the spring of the plunger forces thelatter into the recess 16, thus again locking the sleeve 13 againstrotation.

The exterior of the sleeve 13 is screwthreaded for engagement with theinteriorly screw-threaded sleeve or cylinder 19 on which said sleeve 13is rotatable and so may be raised and lowered thereon, or vice versa.

It is to be understood that the base of the cylinder rests freely on thetop wall of the frame 2, and to this frame is connected by the screws 10the annular flange-11 which 'freely embraces said shoulder, see Fig. 2.

The fiange 11 is carried by the plate 9, said plate having on itsopposite sides elongated slots 9? which receivebosses 2e rising from theframe 2, by which provision the cylinder 13 and connected parts may bemoved to the right and left for centering tubes and rods in saidcylinder 13 of ldifferent dialneters, the screws A10 'whenv tightenedthus serving to retain vsaid cylinder in adjusted position, withoutliabilty to turn.

On the side of said sleeve l19 is the boss 2O in which is the slidablecutter carrier 21 which is adapted for cutting a screw thread on a tube,and the other cutting edge 27 of which is adapted for cutting through orsevering a tube, it being evident that by properly advancing the carrier21 in the boss 20, the cutter 25 may be turned so to present either ofits cutting edges to the tube outside of the boss 20, while the othercutting edge remains in the boss preventing rotation of said cutter.

The boss is provided withV a screw 28 whose point freely enters thelongitudinally extending slot or way 29`in the carrier 21 preventingArotation of the latter, see Fig. 4.

It will now be seen that as the sleeve 13 is held interlocked with thestock 2 and consequently with the handle 7, said sleeve may be rotatedby the latter on the sleeve 19. rlhen vthe sleeve 13 is rotated and thecutter 21 is lforced in to the required extent by the opera-tion kof thehead 23 of the screw 22, and so the cutting edge 26 cuts on the tube ascrew thread as sho-wn at 30,Fig. 2.

When the sleeve 19 is lowered to full extent, it is frictionally held onthe sleeve 13. Then the plunger 15 is drawn out, thus unlocking thesleeve 13. The cutter 25 is reversed whereby its edge 27 is presented tothe tube. The sleeve 19 is now rotated, and the sleeve 13 rotates withit as one, when said cutter is moved in to the required extent by theoperation of the head 23 so as to cut @through the tube, and so severthe same, as shown in Fig. 5.

In order to assist in centering the tube, I employ the ring 3 1, theopening of which may be varied to suit tubes of different diam-.eters,.said ring being located in the cylinder 19 and embracing theadjacent portion of the tube, las most plainly shown in Fig. 2, theeffect of which is evident.

Attention is directed to the fact tliattlie forked head 6 which acts asa clamp or vise like jaw, acts to center the tube (or rod)Y which isengaged therewith and is applicable to tubing and rods of differentdiametersV working effectively therewith.

Having thus described my invention what I claim as new and desire tosecure by Letters atent, is Y 1. In a tube threading and severing devicea primarycylinder and an auxiliary cylinder movable thereon, saidcylinder having engaging screw threads, a two part reversible cutter onsaid auxiliary cylinder, and means on the device adapting said auxiliarycylinder to be rotated with said primary cylinder for severing purposes,or independently thereof for threading purposes.
